1. While good nutrition is very important for a breastfeeding mother, the composition of breast milk remains relatively stable regardless of the mother's diet. Factors other than maternal diet may play a role in breast milk fatty acid composition. FA levels in breast milk and maternal diet are highly correlated. The amount of v ariability in human milk attr ibutable to diet re mains mostly unkn own.. The maternal diet seems to have no impact on the macronutrient milk composition. B. . One of them is the maternal diet. Factors other than maternal diet may play a role in breast milk fatty acid composition. Exposure to excessive amounts of mercury through breast milk can pose a risk to a baby's developing nervous system. Many maternal, infant and physiological factors influence the composition of breast milk. Methods Breast milk of full expression of one side breast from 436 urban Chinese lactating mothers at 5-11 days, 12-30 days, 31-60 days . The concentrations of various forms of fatty acid in breast milk varied. Methods: A total of 21 breast-feeding mothers aged between 17 and 38 years who fasted during Ramadan month and volunteered to give milk samples were surveyed. the macronutrient composition of human milk varies within mothers and across lactation but is remarkably conserved across populations despite variations in maternal nutritional status.13as shown in table 1, the mean macronutrient composition of mature, term milk is estimated to be approximately 0.9 to 1.2 g/dl for protein, 3.2 to 3.6 g/dl for … A diet low in DHA may result in low concentration of DHA in the breast milk. Methods Lactating rats were divided into: casein control (C): casein diet; soy (S): soybean diet; soy oil control (SOC): casein diet, but with fat content similar to the . 5 That's because the first milk that flows at each feed is lower fat milk, so the concentration of fat is higher in the milk that's left. This is not consis-tent with results of other studies, reporting an impact of maternal fat consumption on the fat composition of breast milk. For each mother considered in the studies, the relation between maternal nutrition and breast-milk composition was estimated and quantified by indicators including correlation coefficients, means within subgroups, estimates from regression models, or P values from comparison tests. was set up under the chairmanship of Dr. Fred Sai to review the interrelationships between maternal diet, breast−milk production, and the return of fertility during lactation: the main components are summarized in the diagram. The impact of maternal diet on the concen-tration of fat-soluble vitamins in human milk was stud-ied. Our aim was to investigate the effects of supplementing a maternal high-fat/sucrose (HFS) diet with prebiotic oligofructose (OFS) on milk composition in . Regional differences were found in breast milk composition. These interrelationships are of major importance to maternal and child health, particularly in the 1 Milk fat provides 50% of the energy in breastmilk, and the types of fats that mothers eat influences the types of fat in breastmilk. Most seafood contains mercury or other contaminants, however. The maternal diet may influence the unique composition of breast milk. 3.8. Most newborns have sufficient iron stored in their bodies for about the first 6 months of life depending on gestational age, maternal iron status, and timing of umbilical cord clamping. DOI: 10.1038/s41598 . This study intended to profile the composition of fatty acid (FA) and triacylglycerol (TAG) in Chinese breast milk and to explore its association with maternal diet. Some vitamins and minerals can be impacted when the mother is under and/or malnourished .Other nutrients in breast milk, including fatty acids, are influenced by maternal nutrition .Linoleic (LA) and α-linolenic acid (ALA) are omega 6 (n-6) and omega 3 (n-3) fatty . Conclusion: Maternal dietary intake, particularly fatty acids, and some micronutrients, including fat soluble vitamins, vitamin B 1, and vitamin C, was related to their content in breast milk composition. There are multiple misconceptions concerning the breastfeeding mother's diet and its adverse impact on breast milk composition and the breastfed child's health, which might lead to breastfeeding cessation. Medicina 2019 , 55 , 173 4 of 12 "Long-chain polyunsaturated fatty acids (LCPUFA) are essential for infant growth and development, and amounts in breast milk depend on maternal diet and body stores. Ann Acad Med Singapore 2010;39:675-79 Fat has been proven to be a critical component of breast milk by providing energy and important nutrients that are fundamental to the development of the central . composition of maternal gut microbiome. Breast milk sam- Fat content and FA composition of breast milk were associated with maternal age, BMI, supplement use and infant age. Maternal Diet and Breast Milk Composition How to Tell If You Have Low-Quality Breast Milk. The amount of variability in human milk attributable to diet remains mostly unknown. Dietary intakes of EPA, DHA, n-3 FA, n-6 FA, SFA and PUFA were positively correlated with the corresponding FA in the milk samples. The cholesterol content of breast milk is highly variable and is related to the duration of breastfeeding, maternal age, maternal diet, season and place of residence. Immediately after birth, colostrum, the first HBM produced after birth, contains 15-20 g/L fat, but it gradually increases with lactation, reaching 40 g/L in mature milk. This study aimed to assess the levels of dietary polyphenols and their microbial-derived metabolites in the breast milk of Hong Kong lactating women, and how maternal diet correlated with the phenolic composition in breast milk. These interrelationships are of major importance to maternal and child health, particularly in the 1 A mother's need for iodine and choline increases during lactation. We found that, the breast milk composition is fairly constant and is not affected by maternal nutrition, or dietary intake. concentrations of healthy urban Chinese mothers at different lactation stages, to expand the database of milk composition of Chinese population, and to examine whether dietary or other maternal factors can affect the levels of macronutrients in breast milk. lactation benefits the mother through increased fitness and improved body composition. Furthermore, Seferovic, et al. Conclusions: Differences exist in breast milk fatty acid composition in dif-ferent ethnic groups in the same region, although no difference was demonstrated in the diet analysis. infant colic. The maternal diet seems to have no impact on the macronutrient milk composition. fructose is detectable in human breast milk and is positively associated with all components of body composition at 6 months of age. Vitamins and minerals present in breast milk include: Vitamin A Thiamin or vitamin B1 Riboflavin or vitamin B2 Pyridoxine or vitamin B6 Cobalamin or vitamin B12 Vitamin D Iodine Iron Copper Zinc The maternal diet may not always be optimal. For this reason, in some countries, the recruitment of vegan lactating women as milk donors is excluded by milk banks. Iodine can be found in dairy products, eggs, seafood, or in iodized table salt. The mother's milk is a rich source of carbohydrates, complex proteins, lipids, and various biologically active additives. Different studies determined the associations and effects of some maternal dietary intake of micro and macronutrients and its reflection in human milk. The largest evidence, in terms of number of articles, for any link between maternal diet and a nutritive property of breast milk came from 3 studies that supported the link between fish consumption and high docosahexaenoic acid in breast milk and 2 studies that reported a positive correlation between dietary vitamin C and milk concentrations of this vitamin. In addition, method of breast milk expression, handling, and storage can also influence its contents. Proximal Constituents. the 3 ethnic groups. The Dietary Guidelines for Americans recommend lactating parents consume 290 mcg of iodine and 550mg of choline daily throughout the first year postpartum. While the outcomes of these studies showed associations of maternal diet with breastmilk composition only one well controlled study has been done to address the effects of following a diet (low carbohydrate or . The fatty acids of breastmilk vary in relation to maternal diet. Breast milk from healthy and well-nourished mothers is the preferred form of infants' feeding in the first six months after parturition, and breastfeeding in this period supports the normal growth and development of new-born infants. A positive correlation was found between the saturated ( p <0.05) and polyunsaturated ( p <0.01) fatty adds of maternal diet and breast milk. . Caffeine in your breast milk might agitate your baby or interfere with your baby's sleep. Multiple studies have also focused on the amount of DHA passed in breastmilk and linked it to maternal consumption of fatty fish (2). Breast milk composition is influenced by habitual diet, yet little is known about the short‐term effects of changes in maternal diet on breast milk macronutrient concentrations. Lipid = 3-5% in mature milk; provides ½ the calories in human milk Effect of maternal diet on fat composition Fatty acid profile reflects dietary intake of mother Very dec. fat diet with adequate CHO & protein, milk is inc. in medium-chain fatty acids Breast milk from healthy and well-nourished mothers is the preferred form of infants' feeding in the first six months after parturition, and breastfeeding in this period supports the normal growth and development of new-born infants. These data imply that maternal diet is an important environmental factor for prolonged jaundice among breast-fed infants. Although prophylactic maternal dietary restrictions are not recommended, mothers all over the world are often recommended to avoid certain foods, due to cultural beliefs, social pressure . A mother's capacity to produce milk of sufficient quantity and quality to support infant growth is resilient and remarkably resistant to nutritional deprivation. Despite the great importance of an adequate maternal nutritional state, serum deficiencies in vitamins A, E, C, B2, B1, calcium and zinc are observed in pregnant mothers and breast milk, being important to identify and prevent these imbalances before conception and during pregnancy and lactation. Maternal diet shapes the composition and diversity of breast milk microbiota, with the most important contributions coming from dietary fiber and both plant and animal protein intakes. BACKGROUND It is widely reported . Conclusion Human milk is an extremely complex biological system . Learn More. The average fat content was observed to be 3.31g in 100ml of breast milk. During the first month postpartum, breast milk changes through three stages: colostrum, transitional milk and mature milk. Breast milk is a dynamic fluid and its content changes with duration of lactation and varies between and among women. Diet and Breast-milk Composition. Breast milk composition partially depends from maternal BMI, with only a higher carbohydrate concentration in the obese women. Maternal diets were classified as 1) high intake of plant protein, fiber, and carbohydrates or 2) high intake of animal protein and lipids. Conclusion 22. The relation between the maternal diet and the milk microbiota needs further research because it has a key impact o … Conclusion Human milk is an extremely complex biological system . Furthermore, it remains unknown how potentially modified human milk composition, determined by maternal factors, may influence the growth and development of infants and children. Many factors can affect the volume and composition of breast milk. despite variations in the maternal diet or the mother's body stores. However, milk production normally affects maternal body composition and nutritional status, and lactating women have increased nutrient demands. Methods: Dietary intake of 77 lactating women was investigated by 24-hour diet recalls and breast-milk sam-ples were taken at the same occasions. Numerous studies indicated that maternal diet can influence FA composition of the milk lipid fraction. This is not consistent with results of other studies, reporting an impact of maternal fat consumption on the fat composition of breast milk. This study's objectives include: 1) develop a better understanding of the composition and structures of breast milk over the early stages of lactation with specific emphasis on the glycans and lipids; 2) how glycan diversity relates to maternal and infant gut microbiota with an emphasis on bifidobacteria species; 3)how milk composition and structure relate to maternal health and diet.
